Caps and plugs are essential components in hydraulic systems used to seal off the end of hoses, pipes, or fittings to prevent fluid leakage and contamination when not in use. They are usually made of durable materials such as steel, stainless steel, or brass and are available in a variety of sizes and thread types to match the hydraulic system's specifications.

Hydraulic caps and plugs come in two main types: thread-on and snap-in. Thread-on caps and plugs screw onto the end of the hydraulic component to create a secure seal, while snap-in caps and plugs are designed to snap into place on the hydraulic component's opening.
